Re: Err....a fly in the lycra?
Yeah, UK legislation can get in the way of new takes on personal transport. For example, BMW made a scooter with a roll cage, the C1, the idea being that you didn't need the hassle of donning leathers and a helmet. UK law says that that a helmet is still a legal necessity when riding a C1, even though wearing a helmet would be dangerous due to risk of neck strain in the event of a collision.
Many countries deemed the use of seatbelts in conjunction with wearing a helmet to be unsafe. The added strain on the riders neck from the added weight of the helmet could cause significant injury to the restrained rider even in a low speed head-on collision. Germany, Switzerland, Italy, France, Israel and Spain authorities were quick to allow an exception to the helmet law for the C1. However, poor C1 sales in the United Kingdom may in part be attributable to the British government's refusal of BMW's request to change helmet regulations for C1 riders.
Some cities in the USA placed an onus on employers to provide off-street storage for bicycles - fear of theft deters some people from cycling to work.
